Overture Ensemble Service Orchestrator (ESO) is the only carrier-class open network functions virtualization (NFV) solution providing analytics-driven orchestration. ESO provides management of the complete NFV service lifecycle for any open virtualized network function (VNF.)

The award-winning ESO coordinates virtual resources and physical network elements to create, activate and assure services using one or more virtual network functions. ESO helps communication service providers (CSPs) and mobile operators achieve the greatest cost savings and respond quickly and appropriately for optimized revenue generation and profitability.

ESO supports the entire lifecycle of a VNF-based service starting with the VNF onboarding to creation of the service through maintenance to the tear down of the service and resource reclamation.

Cutting costs is not enough

NFV is often touted as a means to cut costs. Both capital (CAPEX) and operational (OPEX) reductions are possible with the deployment of centrally controlled virtual functions running on standard server platforms. While reducing spending is always desirable, service agility and new revenue represent a far greater opportunity with NFV.

ESO is essential for service innovation

With the carrier-class ESO solution, services can be enabled in minutes rather than months; they can be dynamically changed according to network conditions; they can be enabled for a short period of time, and charged accordingly; and new services can be introduced far more quickly at far less cost than previously possible. ESO drives new revenue and increasing profitability.

ESO features a full lifecycle event-driven orchestration system. Lifecycle processes are implemented using a BPMN 2.0 compatible workflow engine making it completely field extensible and adaptable to the service provider’s operational processes. Further, NFV lifecycle processes are policy driven via a tightly integrated rules engine. Lifecycle control workflows and tasks can be fully modified at run-time in accordance with operator policies.

ESO supports the placement of VNFs in centralized data centers as well as distributed placement across multiple data centers, central offices, points of presence or customer-located compute platforms.

ESO is capable of instantiating any arbitrary combination of VNFs from multiple software vendors. ESO can automatically optimize placement of these VNFs based on pre-defined policies or dynamic conditions such as network congestion or compute performance degradation.

Service providers may initially deploy ESO using its built-in, web-based graphical user interface and standard workflow. They can transition to a fully automated environment by integrating ESO interfaces into higher level systems using a set of open APIs and customizing the VNF management workflow.

ESO uses OpenStack cloud controller bundled with the system to manage the virtual compute environment, including virtual machines, Open vSwitches and top-of-rack data center switches. For steering packet flows from physical network equipment such as Carrier Ethernet access and aggregation switches to and from the VNFs, ESO seamlessly works with Overture’s Ensemble Network Controller (ENC) to control these flows. If ENC is not installed in the network, ESO can be integrated with any third-party network controller to perform this function.

ESO use cases

ESO is particularly beneficial when utilized for:

• Virtual Enterprise Customer Premises Equipment (vE-CPE). This use case is focused on replacing the multiple network elements required to deliver a number of managed enterprise services, including managed router, firewall, VPN, PBX, and application acceleration.

• Virtual Evolved Packet Core (vEPC). vEPC is a virtualized version of the advanced architecture that consolidates voice and data networking framework to connect users on a Long-Term Evolution (LTE) network.

• Virtual Test Head (vTH) and Virtual Network Probe (vNWP). These use cases involve placing virtual traffic generation and measurement systems at various points in the network to monitor network performance or execute troubleshooting tasks.
